），
User gives the module instruction (HEX format): C1 C1 C1,
Module returns the present configuration parameters.
For example, C0 00 00 1A 17 44.
7.3 Reading version number
Instruction format Description
C3+C3+C3
In sleep mode
（
M0=1
，
M1=1
）
,User gives the module instruction (HEX format): C3 C3 C3,Module
returns its present version number, for example C3 32 xx yy. the second bytes means frequency. 32
here means the frequency is 433MHZ, 38 means frequency is 470MHz, 45 means frequency is;
868MHz, 44 means the frequency is 915 MHz, 46 means the frequency is 170MHz; xx is the
